[EnergyPlus_Support] Pump: Variable Speed - Rated pump head




Maybe it's a banal question but, what does E+ mean with the  "Rated pump head"?
Is it the maximum pressure which the pump can withstand?
So it has nothing to do with the graph head[Pa]-flow[m3/h]... right? Or better, the "pressure working condition "of the pump must be compatible with the "rated pump head".
I don't undestand this value for the building I'm modelling. It's a 5 storey residential building and this pump is the only pump which provides the circulation of the heating fluid. The heating system is a radiant floor heating, how should I choose a pump? I don't know the losses of hydraulic load and so the needed head.

Thanks
